System-wide Dynamic Performance Metric for IBR-based Power Networks
Rodrigo Bernal, Taulant Kerci, Federico Milano
In power networks based on Inverter-Based Resources (IBRs), fast controllers cause frequency and voltage dynamics to overlap. Thus, it becomes critical to assess the overall dynami…
Coherency Control in Power Systems
Rodrigo Bernal, Ignacio Ponce, Federico Milano
This paper proposes a coherency control strategy for Inverter-Based Resources (IBRs) to establish coherence among power system devices. Using the equivalence of the Complex Frequen…
Coherency among Power System Devices
Ignacio Ponce, Rodrigo Bernal, Federico Milano
The paper proposes a novel general definition of coherency among power system devices of any type. The proposed approach is thus not limited to synchronous machines. With this aim,…
Generalized Swing Control Framework for Inverter-based Resources
Rodrigo Bernal, Federico Milano
This paper proposes a novel control framework designed for Inverter-Based Resources (IBRs), denoted as Generalized Swing Control (GSC). The proposed GSC framework generalizes the d…
Transient Slack Capability
Rodrigo Bernal, Federico Milano
This paper introduces the concept of Transient Slack Capability (TSC), a set of three necessary device-level conditions to ensure stability under sustained power perturbations. TSC…
A Complex Frequency-Based Control for Inverter-Based Resources
R. Bernal, F. Milano
This paper proposes a novel control for Inverter-based Resources (IBRs) based on the Complex Frequency (CF) concept. The controller's objective is to maintain a constant CF of the…
